DAVID T. WILLIAMS, OF PATERSON, NEW JERSEY, ASSIGNOR TO VACUUM ENGINEERING COMPANY, A CORPORATION OF NEW YORK.

PIPE-FITTING.

To all whom it may concern:

Be it known that 1, DAVID T. WILLIAMS, a British subject, and a resident of Paterson, county of Passaic, State of New Jersey, have invented certain new and useful Improvements in Pipe-Fittings, of which the following is a full, clear, and complete disclosure.

My invention relates to pipe fittings, and particularly to that class of pipe fittings in which two ipes or conduits are connected to a single 0 ject, such as a valve, cook, or similar device, composed of integral or rigidly-connected parts.

My invention is especially applicable to pipes which pass through a wall or partition of a building or room, and the warts of the device are so arranged that the pipes may be installed and the walls of the building or room completely finished, after which the valve or similar device may be placed in position upon said wall without the necessity of removing any portion of said wall or partition. The device is so arranged that all the parts are accessible and easily adjustable in their correct positions.

My invention is of special utility in connection with vacuum or pneumatic cleaning systems, where both the suction and waterpipes pass through the walls of the rooms at the different floors and are connected to a single valve which controls both said suction and said water su ply.

IIeretofore, in t e construction of buildings and the installation of suction and water pipes for vacuum or pneumatic cleaning systems, it has been necessary to leave a considerable portion of the wall adjacent said pipes unfinished, so that access could be had to the branches which enter the room, in order that the usual or ordinary pipe connections might be screwed in place. This means of placing the valves and their connecting pipes in position, has not only delayed the ishing of the walls of the room, but has made it impossible to make the finish as neat and uniform in appearance as it would be if all done at one time.

The object of my invention, therefore, is to provide a connection for connecting a valve or similar object to two adjacent ipes, in a simple and efiicient manner, and a so to provide a connection that is finished in a pearance and one that may be installed without injury to, or displacement of, any of the parts surrounding the pipes or conduits.

Specification of Letters Patent.

Serial No. 422,107.

For the sake of illustration, I have shown my improved pi e fittings in connection with a unitary doub e-acting valve, which controls two passages through the same, in this instance one passage being for the suction and the other for the water supply in connection with the vacuum or pneumatic cleaning system.

For a full and detailed description of one form of my invention which 1 at resent deem preferable, reference may be ha to the following specification and the accompanying drawing, in which the figure thereof indicates my improved pipe fittings in elevation, the essential parts thereof being shown in vertical cross section.

Referring to said drawing, the numeral 1 indicates a com aratively large suction pipe, and the numerzil 2 a smaller or water-supply pipe. These pipes run vertically through the building, and have branches 3 and 4 at each floor on which the supply from said pipes is to be used. The branches 3 and 4 terminate in screw-threaded ends 5 and 6, the screw thread of said ends being preferably arallel in contra distinction to the tapering screw-threads of ordinary pipe fittings.

Upon the inner surface of the wall 7 of the room I place a suitable plate 8, which may be of circular or of any other preferred or ornamental outline, and which has a lug 9 projecting from its inner side, so located as to extend within the passage 10 in the wall through which the branches 3 and 4 extend. The lug 9 is for the purpose of supporting and holding in position the plate 8 and the parts carried thereby. The plate 8 is held in firm contact with the surface 7 by means of nuts 11 and 12, which engage screw-threaded ends 5 and 6 of the branches 3 and 4, and when screwed firmly upon the plate 8 holds said plate firmly against the wall and the pipes 3 and 4 securely in their relative positions. The plate 8 is provided with a marginal flange 13, within which is adapted to be seated the flange 14, carried by the valve 15 or similar device, to which the pipes 3 and 4 are con nected. The flange 14 is preferably offset as indicated at 16, so as to provide a recess or recesses, within which the nuts 11 and 12 may be seated.

The double tubular portion 17 of the valve or similar device is provided with cylindrical recesses 18 and 19, within which the screwthreaded ends 5 and 6 may pass, and which are also adapted to contain the gaskets or packing 20 and 21. The flange 14 is provided With suitable holes, through which pass the screws or bolts 22, and it will be seen that when these screws or bolts are turned up, they will draw the said flange and its connected valve or similar device toward the plate 8, and will cause the gaskets 20 and 21 to be firmly held in position, so as to prevent leakage between the end of the pipes 3 and 4 and the tubular portion 17 of the said valve or similar device. the gaskets or packings 20 and 21 may be placed at any other preferred or convenient point, but I have found that when they are located as indicated in the drawings, more satisfactory results are obtained.

Having thus described my invention, I do not wish to be understood as being limited to the eXact details of form or arrangement of parts set forth, for various changes may be made without departing from the spirit and scope of my invention; but

What I claim and desire to protect by Letters Patent of the United States is:

1. In combination with a plurality of tubular conduits, a base through which said conduits pass and adapted to be seated against a wall, means for holding the ends of said conduits in a fixed position relative to said base, a unitary device having passages corresponding to said conduits, and means engaging said base for forcing said device into fluid-tight connection with the ends of said conduits.

2. In combination with a plurality of tu- It is obvious that a bular screw threaded conduits, a base through which said conduits pass and adapted to be seated against a wall, nuts [or holding the ends of said conduits in a iixed position relative to said base, a unitary device having passages corresponding to said conduits, and means engaging said base for forcing said device into lluid-tight connection with the ends of said conduits.

3. In combination with a plurality of tubular screw threaded conduits, a base through which said conduits pass and adapted to be seated against a wall, nuts upon the ends of said screw-threaded conduits and engaging said base, a unitary device having passages corrcspoiuling to said conduits and also having a llange extending parallel with the said base, and means engaging said flange and said base for forcing said device into fluid-tight connection with the ends of said conduits.

l. In combination with a plurality of tubular scrcw-threaded conduits, a base-plate through which said conduits pass and adapted to be seated against a \\'all,nuts upon said screw-threaded conduits and. en aging said base-plate, a unitary device having passages corresponding to said conduits and having recesses adjacent said passages, into which the ends of said conduits extend, fluid-tight packing in said recesses, and means for foreing said device toward said base-plate.

Signed this 16th day of March 10055.
